Hey guys today I put my car on the dyno for the first time and here's what I made in numbers
It was a mustang dyno
Alittle about my car
2016 focus st st2
Magnaflow cat back
Cfm downpipe
Cobb drop in filter
Depo intake tube
Depo 3.5 intercooler
Cobb ap running stritafied stage 3 flash tune
Rmm

We had some trouble at first because the traction control was kicking in and killed the power

I haven't put in colder plugs should I ?

Does it look like a decent run for the mods I have I was debating doing a log and sending it in to the tuner
Also I was told mustang dynos show a lower number then dyno jet by 12-15%

Colder plugs won't help you.

What fuel are you using? Looks like 91 octane to me.

Idk, still seems low, especially in the torque department.

Time to get a full tune and Strat to check out the logs.

Somethings up.

Pull a few logs and check your max boost, boost hold, and ign corrections.

Yep that looks to be a good starting point, good luck! Nice car too. Also next time you dyno, try to see if the dyno operator can have a secondary fan running right into your IC. It'll help keep the charge air temps down a bit better for max power.

I am no dyno expert, but could the fact that the dyno is in 4wd mode have some impact on the numbers? I am not sure how mustang does their linking between the front a rear rollers, but if the front is linked to the rear and the car has to spin 4 rollers with just 2 wheels could that not lead to lower numbers? I don't think that this is the case, but hey just an observation.

I don't know.. every dyno is different and Mustang dynos are typically low. This particular one might be reading exceptionally low but its impossible to tell without comparing to other dynos.

OP, take some logs and put them through virtual dyno and compare before you do anything else.
